Description

Vehicle window glass, vehicle door, and vehicle

[0001] The present invention relates to a vehicle window glass, a vehicle door, and a vehicle.

[0002] Patent Document 1 discloses a vehicle in which a window glass is attached to a door body so as to be movable up and down. A step is formed at the upper end of the window glass of this vehicle.

[0003] Japanese Patent Laid-Open No. 7-137535

[0004] In the one disclosed in Patent Document 1, the window glass in which a step is formed is formed by injection molding a resin glass. Therefore, the manufacturing cost becomes high.

[0005] The present invention has been made under the above circumstances, and an object thereof is to provide a vehicle window glass, a vehicle door, and a vehicle capable of suppressing the manufacturing cost while forming a step at the end of the window glass.

[0006] In order to achieve the above object, a vehicle window glass according to the present invention is a vehicle window glass that is attached to a vehicle door so as to be movable up and down, and includes a first glass and a second glass that is bonded to the first glass and is disposed on the outer side of the vehicle. The end of the first glass is formed to protrude more than the end of the second glass, so that the end of the first glass protrudes more than the end of the second glass to form a step between the end of the first glass and the end of the second glass.

[0007] According to the present invention, the second glass is bonded to the first glass. And, between the end of the first glass and the end of the second glass, the end of the first glass protrudes more than the end of the second glass to form a step. Therefore, it is possible to suppress the manufacturing cost while forming a step at the end of the window glass.

This is a cross-sectional perspective view showing a part of the front left door of Figure 1A. This is a cross-sectional view taken along line III-III in Figure 1A. This is a perspective view of a window glass according to Embodiment 1. This is a cross-sectional view taken along line V-V in Figure 4. This is a cross-sectional view of a window glass of a vehicle according to Embodiment 2. This is a perspective view of a window glass according to Embodiment 2. This is a cross-sectional view taken along line VIII-VIII in Figure 7.

[0009] Embodiment 1. Hereinafter, the vehicle window glass, vehicle door D, and vehicle 100 according to Embodiment 1 will be described with reference to the figures. For ease of understanding, mutually orthogonal XYZ coordinates will be set and referred to as appropriate. As shown in Figures 1A, 1B, and 2, the X-axis direction of the XYZ coordinates is the vehicle width direction of the vehicle 100, the Y-axis direction is the front-rear direction of the vehicle 100, and the Z-axis direction is the vehicle height direction of the vehicle 100. In each figure, the same reference numerals indicate the same or corresponding parts.

[0010] Vehicle 100, as shown in Figures 1A and 1B, for example, comprises a body 110, tires 120, a gasoline engine, vehicle doors D with movable windows, and other automotive parts. Vehicle 100 is, for example, an automobile equipped with a gasoline engine for driving the tires 120. However, it is not limited to this. Vehicle 100 may also be an electric vehicle equipped with a drive motor, a hybrid vehicle equipped with both a gasoline engine and a drive motor, an automobile equipped with a diesel engine, and the like.

[0011] Vehicle doors D are provided on the left and right side doors of a vehicle 100 equipped with a window E. In this embodiment, the left front door will be described, but the other doors have a similar structure. Vehicle door D comprises a door body 10 and a door frame member 25. In addition, as shown in Figures 2 and 3, vehicle door D comprises a window glass 30, a window frame rubber member 40-1, and a door regulator 90 for raising and lowering the window glass 30, in addition to the door body 10 and the door frame member 25. The aforementioned window E is provided on the side door and comprises a window glass 30 and a window frame rubber member 40-1.

[0012] As shown in Figures 1A and 1B, the door body 10 is provided to be openable and closable from the vehicle 100 so that the driver can get in and out of the vehicle 100. In this embodiment 1, the door body 10 is exemplified as a hinged door that swings outwards from the vehicle around a pivot point as shown in the swing direction A1. However, it is not limited to this. The door body 10 may also be a sliding door that opens and closes parallel to the surface of the vehicle body 110. As shown in Figures 2 and 3, the door body 10 is provided with a window glass 30. The window glass 30 is provided to be able to move up and down relative to the window frame rubber member 40-1 as shown in the up and down direction A2. For example, the door body 10 has an outer panel 11 and an inner panel 12, and the lowered window glass 30 is housed between the outer panel 11 and the inner panel 12.

[0013] Since the door frame member 25 is fixed to the door body 10, when the door body 10 is opened or closed, it opens and closes together with the door body 10, along with the window glass 30 and the like. A window frame rubber member 40-1 is attached to the door frame member 25. Furthermore, the door frame member 25 is made of a material with higher rigidity than the window frame rubber member 40-1 in order to increase the strength of the vehicle door D. In this embodiment 1, the vehicle door D is not a frameless door without a door frame member 25, but a framed door with a door frame member 25. The vehicle door D is opened and closed from the vehicle 100 when the driver gets in or out of the vehicle 100.

[0014] The window glass 30 is a transparent plate-shaped member capable of closing the window E of the vehicle 100. The window glass 30 is provided so as to be able to move up and down to close or open the window E, for example, when the window E is opened, the air inside the vehicle 100 is ventilated. The window glass 30 is in a fully closed state when its end moves upward (+Z direction) and contacts the window frame rubber member 40-1 attached to the door frame member 25. The window glass 30 is in a fully open state when it moves downward (-Z direction) and is stored between the outer panel 11 and the inner panel 12 of the door body 10. In the fully closed state, the window glass 30 has a shape that slopes inward towards the vehicle as it approaches its upper end. The upper end of the window glass 30 moves outward as the window glass 30 moves downward (-Z direction), and a gap is created between the upper end of the window glass 30 and the window frame in the vehicle width direction (X-axis direction). In this embodiment 1, the window glass 30 is a laminated glass comprising a first glass 31 and a second glass 32. More specifically, in this embodiment 1, the window glass 30 comprises a first glass 31, a second glass 32, and a resin part 33 (resin layer).

[0015] The first glass 31 is formed from a plate-like member having a uniform thickness t1. The thickness t1 of the first glass 31 is, for example, 2 mm to 3.5 mm. The roof portion 31a, which is the upper (+Z side) end of the first glass 31, is the part that contacts the window frame rubber member 40-1 located on the door frame member 25 when the door is fully closed, as shown in Figure 3. The roof portion 31a of the first glass 31, which is its upper (+Z side) end, is formed to protrude more than the roof portion 32a of the second glass 32, which is its upper (+Z side) end. As a result, a step 34 is formed between the roof portion 31a of the first glass 31 and the roof portion 32a of the second glass 32.

[0016] Furthermore, as shown in Figures 4 and 5, the rear end (+Y side) 31b of the first glass 31 is formed to protrude further than the rear end (+Y side) 32b of the second glass 32. As a result, a step 34 is also formed between the rear end (+Y side) 31b of the first glass 31 and the rear end (+Y side) 32b of the second glass 32. The vehicle door D in Figures 4 and 5 represents the front right door. In this embodiment 1, the front end (-Y side) 31c of the first glass 31 is formed to protrude further than the front end (-Y side) 32c of the second glass 32, and a step 34 is also formed between the front end (-Y side) 31c of the first glass 31 and the front end (-Y side) 32c of the second glass 32. Furthermore, the lower (-Z side) end 31d of the first glass 31 is not formed to protrude more than the lower (-Z side) end 32d of the second glass 32. Since the lower end 31d of the first glass 31 and the lower end 32d of the second glass 32 are housed in the door body 10, there is no need to create a flush surface, and therefore no step 34 is formed there.

[0017] The second glass 32 is formed from a plate-like member having a uniform thickness t2. The thickness t2 of the second glass 32 may be the same as or different from that of the first glass 31, for example. The upper end surface of the roof portion 32a, which is the upper (+Z side) end of the second glass 32, is positioned close to or in contact with the window frame rubber member 40-1 when fully closed, as shown in Figure 3. The second glass 32 is bonded to the first glass 31 and is positioned on the outside of the vehicle.

[0018] Furthermore, the rear (+Y side) end 32b and the front (-Y side) end 32c of the second glass 32 are positioned without contact with the window frame rubber member 40-1, as shown in Figure 5. In this embodiment 1, the rear (+Y side) end 32b and the front (-Y side) end 32c of the second glass 32 are positioned without contact with the window frame rubber member 40-1 from the fully closed state to the fully open state.

[0019] The resin portion 33 is a resin layer made of an adhesive used to bond the second glass 32 to the first glass 31. The resin portion 33 is formed from a permeable material. For example, the resin portion 33 is made of PVC (polyvinyl chloride). The thickness of this resin portion 33 is formed to be, for example, 0.5 mm to 1.0 mm.

[0020] The window frame rubber member 40-1 is made of an elastic material. The window frame rubber member 40-1 guides the raising and lowering of the window glass 30 and suppresses vibrations of the window glass 30 while driving or when the door is closed. The window frame rubber member 40-1 has a lip portion 50, a window glass holding portion 60, and a base portion 70.

[0021] As shown in Figure 3, the lip portion 50 is made of an elastic material. When the window glass 30 rises and contacts the window frame rubber member 40-1, thereby fully closing the window E, the lip portion 50 is pressed by the window glass 30, causing it to elastically deform and be retracted inside the vehicle relative to the window glass 30. When the window glass 30 descends from the fully closed position and the window E opens, the elastic deformation of the lip portion 50 is released, causing it to elastically recover, and the outer end 50a of the lip portion 50 is formed to protrude outwards from the vehicle.

[0022] The window glass holder 60 is fixed to the door frame member 25. The window glass holder 60 has an end holder 63 that extends in the Y-axis direction and into which the upper end of the window glass 30 fits, and a clamping portion 64 provided on the end holder 63. The clamping portion 64 is shaped to be able to be clamped into a plate-shaped projection 22A formed on the door frame member 25. The lower wall portion 65 provided on the lower side (-Z side) of the window glass holder 60 is shaped to bend when it comes into contact with the upper end of the raised window glass 30.

[0023] The base portion 70 is attached to and fixed to a plate-shaped projection 22B formed on the door frame member 25. The base portion 70 is provided with a window glass holding portion 60 and a lip portion 50. The window glass holding portion 60 is provided at an upper position via a connecting portion 73. The lip portion 50 is formed to protrude outward from the base portion 70.

[0024] A drainage channel 80 is formed between the base portion 70 and the lip portion 50, through which water flowing in from the lip portion 50 passes. The drainage channel 80 is designed such that, for example, water flows to the front or rear side of the vehicle 100 before flowing down below the vehicle 100.

[0025] As described above, in this embodiment 1, as shown in Figure 3, the second glass 32 is bonded to the first glass 31. The roof portion 31a, which is the end of the first glass 31, is formed to protrude more than the roof portion 32a, which is the end of the second glass 32. As a result, a step 34 is formed between the roof portion 31a of the first glass 31 and the roof portion 32a of the second glass 32. In other words, the roof portion 31a of the first glass 31 is made to protrude more than the roof portion 32a of the second glass 32 in order to form a step 34 between the roof portion 31a of the first glass 31 and the roof portion 32a of the second glass 32. Therefore, it is possible to suppress manufacturing costs while forming a step 34 at the end of the window glass 30. Furthermore, the window glass 30 of this embodiment 1 can be applied to frame door type automobiles having a door frame member 25 without changing the existing structure.

[0026] Furthermore, this embodiment 1 includes a resin portion 33 (resin layer) provided between the first glass 31 and the second glass 32, which is formed from resin for bonding the first glass 31 and the second glass 32 together. Therefore, in this embodiment 1, manufacturing costs can be reduced compared to the case where a step 34 is formed at the edge of the window glass 30 by injection molding or the like.

[0027] Furthermore, in this embodiment 1, the roof portion 31a of the first glass 31 is formed to protrude above the vehicle 100 more than the roof portion 32a of the second glass 32. Therefore, by adjusting the thickness of the second glass 32 and the amount of protrusion of the first glass 31 (i.e., the size of the second glass 32), the protrusions and irregularities from the outer surface of the vehicle 100 can be reduced. Thus, a flush surface can be achieved by minimizing the surface difference between the outer surface 30a of the window glass 30 and the outer surface 40a of the window frame rubber member 40-1 and the outer surface 100a of the metal part of the vehicle body 110. By achieving a flush surface, the air resistance of the vehicle 100 can be reduced, wind noise and vibration during driving can be reduced, and the design of the vehicle body 110 can be improved. As a result, in addition to suppressing manufacturing costs, it becomes possible to achieve a flush surface. Furthermore, by adjusting the thickness of the second glass 32 and the amount of protrusion of the first glass 31 (i.e., the size of the second glass 32), a flush surface can be achieved. For this reason, the window glass 30 of this embodiment 1 can be applied to frame door type automobiles having a door frame member 25 without changing the existing structure.

[0028] Furthermore, in this embodiment 1, the roof portion 31a of the first glass 31 is in contact with the window frame rubber member 40-1 when fully closed. The roof portion 32a of the second glass 32 is positioned without contact with the window frame rubber member 40-1 when fully closed. Therefore, by adjusting the thickness of the second glass 32, the protrusions and unevenness from the outer surface of the vehicle 100 can be reduced. Thus, a flush surface can be achieved by minimizing the surface difference between the outer surface 30a of the window glass 30 and the outer surface 40a of the window frame rubber member 40-1 and the outer surface 100a of the metal part of the vehicle body 110. By achieving a flush surface, the air resistance of the vehicle 100 can be reduced, wind noise and vibration during driving can be reduced, and the design of the vehicle body 110 can be improved. As a result, in addition to suppressing manufacturing costs, it becomes possible to achieve a flush surface. Furthermore, a flush surface can be achieved by adjusting the thickness of the second glass 32. Therefore, the window glass 30 of this embodiment 1 can be applied to a frame door type automobile having a door frame member 25 without changing the existing structure.

[0029] Furthermore, in this embodiment 1, as shown in Figure 5, the ends 31b and 31c of the first glass 31 are formed to protrude forward and backward in the front-rear direction compared to the ends 32b and 32c of the second glass 32. Therefore, in this embodiment 1, manufacturing costs can be reduced compared to the case where a step 34 is formed at the end of the window glass 30 by injection molding or the like. In addition to reducing manufacturing costs, the air resistance of the vehicle 100 can be reduced, which can reduce wind noise and vibration during driving and improve the design of the automobile.

[0030] Embodiment 2. In Embodiment 1 described above, as shown in Figure 3, the vehicle door D of the automobile is a framed door having a door frame member 25. However, it is not limited to this. The vehicle door D2 may be a frameless door or a sashless door that does not have a door frame member 25. Hereinafter, Embodiment 2, in which a window glass 30 with a step 34 is applied to a frameless door or sashless door of an automobile, will be described with reference to Figures 6 to 8. For the sake of ease of understanding, XYZ coordinates will be set and referred to as appropriate. Except for the differences described, it will be the same as or equivalent to Embodiment 1.

[0031] As shown in Figure 6, the vehicle door D2 comprises a door body 10, a retaining member 20-2, a window glass 30, window frame rubber members 40-1 and 40-2, and a door regulator 90 for raising and lowering the window glass 30. Since the vehicle door D2 is a frameless or sashless door, when the driver gets in or out of the vehicle 100, the upper end, front end, and rear end of the window glass 30 are exposed when the door is opened and closed from the vehicle 100.

[0032] The door body 10 is provided with a window pane 30 that can move up and down relative to the window frame rubber member 40-1 in the direction of vertical movement A2. For example, the door body 10 has an outer panel 11 and an inner panel 12, and the lowered window pane 30 is housed between the outer panel 11 and the inner panel 12.

[0033] The retaining member 20-2 is a window frame that holds the fully closed window glass 30 in the correct position and allows it to be raised and lowered smoothly. Together with the window glass 30, the retaining member 20-2 prevents rain and wind from entering the vehicle. The retaining member 20-2 has a recessed portion 21 into which the window frame rubber member 40-1 is fitted.

[0034] The window glass 30 is a transparent, plate-shaped member capable of closing the window E of the vehicle 100. The window glass 30 is provided so as to be able to move up and down to close or open the window E, for example, when the window E is opened, the air inside the vehicle 100 is ventilated. The window glass 30 is in a fully closed state when its end moves upward (+Z direction) and contacts the window frame rubber member 40-1 provided on the holding member 20-2. The window glass 30 is in a fully open state when it moves downward (-Z direction) and is stored between the outer panel 11 and the inner panel 12 of the door body 10. In the fully closed state, the window glass 30 has a shape that slopes inward towards the vehicle as it approaches its upper end. The upper end of the window glass 30 moves outward as the window glass 30 moves downward (-Z direction), creating a gap between the upper end of the window glass 30 and the window frame in the vehicle width direction (X-axis direction). In this second embodiment, the window glass 30 is a laminated glass comprising a first glass 31 and a second glass 32, and has the same structure as that of the first embodiment. More specifically, in this second embodiment, the window glass 30 comprises a first glass 31, a second glass 32, and a resin part 33 (resin layer).

[0035] The first glass 31 is formed from a plate-like member having a uniform thickness t1. The thickness t1 of the first glass 31 is, for example, 2 mm to 3.5 mm. The roof portion 31a, which is the upper (+Z side) end of the first glass 31, is the portion that contacts the window frame rubber member 40-1 located on the holding member 20-2 when the window is fully closed. The roof portion 31a of the first glass 31 is formed to protrude more than the roof portion 32a of the upper (+Z side) end of the second glass 32. As a result, a step 34 is formed between the roof portion 31a of the first glass 31 and the roof portion 32a of the second glass 32.

[0036] Furthermore, as shown in Figures 7 and 8, the rear end (+Y side) 31b of the first glass 31 is not formed to protrude beyond the rear end (+Y side) 32b of the second glass 32. As a result, no step 34 is formed between the rear end (+Y side) 31b of the first glass 31 and the rear end (+Y side) 32b of the second glass 32. The vehicle door D in Figures 7 and 8 represents the front right door. Also, in this embodiment 2, the front end (-Y side) 31c of the first glass 31 is not formed to protrude beyond the front end (-Y side) 32c of the second glass 32. No step 34 is formed between the front end (-Y side) 31c of the first glass 31 and the front end (-Y side) 32c of the second glass 32. Furthermore, the lower (-Z side) end 31d of the first glass 31 is not formed to protrude more than the lower (-Z side) end 32d of the second glass 32. Since the lower end 31d of the first glass 31 and the lower end 32d of the second glass 32 are housed in the door body 10, there is no need to create a flush surface, and therefore no step 34 is formed there.

[0037] The second glass 32 is formed from a plate-like member having a uniform thickness t2. The thickness t2 of the second glass 32 may be the same as or different from that of the first glass 31, for example. The upper end surface of the roof portion 32a, which is the upper (+Z side) end of the second glass 32, is positioned close to or in contact with the window frame rubber member 40-1 when fully closed, as shown in Figure 6, unlike the roof portion 31a of the first glass 31. The second glass 32 is bonded to the first glass 31 and is positioned on the outside of the vehicle.

[0038] Furthermore, the rear (+Y side) end 32b and the front (-Y side) end 32c of the second glass 32 are positioned without contact with the window frame rubber member 40-1, as shown in Figure 5. In this second embodiment, the rear (+Y side) end 32b and the front (-Y side) end 32c of the second glass 32 are positioned without contact with the window frame rubber member 40-1 from the fully closed state to the fully open state.

[0039] The resin portion 33 is a resin layer made of an adhesive used to bond the second glass 32 to the first glass 31. The resin portion 33 is formed from a permeable material. For example, the resin portion 33 is made of PVC (polyvinyl chloride). The thickness of this resin portion 33 is formed to be, for example, 0.5 mm to 1.0 mm.

[0040] The window frame rubber member 40-1 is made of an elastic material. The window frame rubber member 40-1 guides the raising and lowering of the window glass 30 and suppresses vibrations of the window glass 30 while driving or when the door is closed. The window frame rubber member 40-1 is formed in a cylindrical shape with the Y-axis direction as the axis. As shown in Figure 6, the window frame rubber member 40-1 has an upper wall portion 41 that contacts the bottom surface 21a of the recessed portion 21, and a lower wall portion 42 that is provided below the upper wall portion 41 (on the -Z side). The lower wall portion 42 is formed opposite to the upper wall portion 41 and is designed to bend when it comes into contact with the upper end of the raised window glass 30.

[0041] The window frame rubber member 40-2 is fixed to the end of the metal part of the vehicle 100. The window frame rubber member 40-2 has a clamping portion 43. The clamping portion 43 is shaped to be able to be clamped onto the plate-shaped protrusion 102 of the metal part of the vehicle 100. The window frame rubber member 40-2 is also provided with a lip portion 50.

[0042] The lip portion 50 is made of an elastic material. When the window glass 30 rises and contacts the window frame rubber member 40-1, thereby fully closing the window E, the lip portion 50 is pressed by the window glass 30, causing it to elastically deform and be retracted inside the vehicle relative to the window glass 30. When the window glass 30 descends from the fully closed position and the window E opens, the elastic deformation of the lip portion 50 is released, causing it to elastically recover, and the outer end portion 50a of the lip portion 50 protrudes outward from the vehicle.

[0043] In the rubber member 40-2 for the window frame, a drainage channel 80 through which water flowing in from the lip portion 50 passes is formed at the base end portion of the lip portion 50. The drainage channel 80 is formed, for example, such that water flows forward or backward of the vehicle 100 and then falls downward of the vehicle 100.

[0044] As described above, in the second embodiment, as shown in FIG. 6, the second glass 32 is bonded to the first glass 31. And the roof portion 31a which is an end portion of the first glass 31 is formed to protrude more than the roof portion 32a which is an end portion of the second glass 32. Thereby, a step 34 is formed between the roof portion 31a of the first glass 31 and the roof portion 32a of the second glass 32. That is, the roof portion 31a of the first glass 31 is made to protrude more than the roof portion 32a of the second glass 32 so as to form a step 34 between the roof portion 31a of the first glass 31 and the roof portion 32a of the second glass 32. For this reason, while forming a step 34 at the end portion of the window glass 30, the manufacturing cost can be suppressed. Further, the window glass 30 of the second embodiment can be applied to a frameless door type or a sashless type automobile having no door frame member without changing the existing structure.

[0045] Further, the second embodiment includes a resin portion 33 (resin layer) provided between the first glass 31 and the second glass 32 and formed of a resin for bonding the first glass 31 and the second glass 32. For this reason, in the first embodiment, the manufacturing cost can be suppressed as compared with the case of forming a step 34 at the end portion of the window glass 30 by injection molding or the like.

[0046] Furthermore, in this second embodiment, the roof portion 31a of the first glass 31 is formed to protrude above the vehicle 100 more than the roof portion 32a of the second glass 32. Therefore, by adjusting the thickness of the second glass 32 and the amount of protrusion of the first glass 31 (i.e., the size of the second glass 32), the protrusions and irregularities from the outer surface of the vehicle 100 can be reduced. Thus, a flush surface can be achieved by minimizing the surface difference between the outer surface 30a of the window glass 30 and the outer surface 40a of the rubber member 40-1 for the window frame and the outer surface 100a of the metal part of the vehicle body 110. By achieving a flush surface, the air resistance of the vehicle 100 can be reduced, wind noise and vibration during driving can be reduced, and the design of the vehicle body 110 can be improved. As a result, in addition to reducing manufacturing costs, it becomes possible to achieve a flush surface. Furthermore, by adjusting the thickness of the second glass 32 and the amount of protrusion of the first glass 31 (i.e., the size of the second glass 32), a flush surface can be achieved. For this reason, the window glass 30 can be applied to frameless door types or sashless types that do not have a door frame member without changing the existing structure.

[0047] Also, in the second embodiment, the roof portion 31a of the first glass 31 is a portion that contacts the window frame rubber member 40-1 in the fully closed state. And the roof portion 32a of the second glass 32 is arranged so as not to contact the window frame rubber member 40-1 in the fully closed state. For this reason, by adjusting the thickness of the second glass 32, protrusions and unevenness can be reduced from the outer surface of the vehicle 100. Therefore, it is possible to achieve a flush surface state in which the surface difference between the outer surface 30a of the window glass 30 and the outer surface 40a on the vehicle outside of the window frame rubber member 40-1 and the outer surface 100a of the metal portion of the vehicle body 110 is minimized as much as possible. By achieving the flush surface state, the air resistance of the vehicle 100 can be reduced, the wind noise and vibration during driving can be reduced, and the design of the vehicle body 110 can be improved. As a result, in addition to suppressing the manufacturing cost, it becomes possible to achieve the flush surface state. Also, by adjusting the thickness of the second glass 32, the flush surface state can be achieved. For this reason, the window glass 30 can be applied to a frame door type automobile having a door frame member 25 without changing the existing structure. Also, in the second embodiment, the same effects as those in the first embodiment can be obtained.

[0048] Also, in the second embodiment, as shown in FIG. 8, the end portions 31b and 31c of the first glass 31 are formed to protrude forward and backward in the front-rear direction from the end portions 32b and 32c of the second glass 32. For this reason, in the second embodiment, compared with the case where a step 34 is formed at the end of the window glass 30 by injection molding or the like, the manufacturing cost can be suppressed. Also, in addition to suppressing the manufacturing cost, the air resistance of the vehicle 100 can be reduced, the wind noise and vibration during driving can be reduced, and the design of the automobile can be improved. Also, in the second embodiment, the same effects as those in the first embodiment can be obtained.

[0049] As described above, the present embodiment has been described, but the present invention is not limited by the above embodiment.

[0050] For example, as shown in Figures 3 and 6, this embodiment includes a resin portion 33 provided between the first glass 31 and the second glass 32, formed from a resin for bonding the first glass 31 and the second glass 32 together. However, it is not limited to this. This embodiment does not need to have a resin portion 33. For example, in this embodiment, the first glass 31 and the second glass 32 may be bonded together using a material other than resin, as long as it can be bonded together. Also, although the resin portion 33 in this embodiment is formed from PVC (polyvinyl chloride), it is not limited to this, and may be formed from a material other than PVC.

[0051] Furthermore, in this embodiment, the lower (-Y side) end 31d of the first glass 31 is not formed to protrude more than the lower (-Y side) end 32d of the second glass 32. However, it is not limited to this. The lower (-Y side) end 31d of the first glass 31 may be formed to protrude more than the lower (-Y side) end 32d of the second glass 32. However, since the lower (-Y side) end 31d of the first glass 31 and the lower (-Y side) end 32d of the second glass 32 are housed in the door body 10, from the viewpoint of manufacturing cost, the end 31d does not need to protrude more than the end 32d.

[0052] Furthermore, in this embodiment, when the window E of the vehicle 100 is opened, the outer end 50a of the lip portion 50 may or may not protrude outward from the outer end of the window frame rubber member 40-1 or the retaining member 20-2.

[0053] The present invention allows for various embodiments and modifications without departing from the broad spirit and scope of the invention. Furthermore, the embodiments described above are for illustrative purposes only and do not limit the scope of the invention. In other words, the scope of the invention is indicated by the claims, not by the embodiments. Various modifications made within the scope of the claims and the equivalent significance of disclosure are considered to be within the scope of the invention.
